Attribution Without a Pixel

Pixel- and cookie-based tracking has been steadily degraded by iOS privacy changes and third-party cookie deprecation. The good news: you can measure what is working without any of it, using first-party data you already own. Here is how.

Why pixel-based attribution broke

Opt-outs, capped attribution windows, and cookie loss mean pixels now miss and misattribute a large share of conversions. Patching them with modeled conversions inside each platform just re-introduces the platform's bias.

The first-party alternative

Your Shopify orders and GA4 exports are first-party and complete. Causal modeling on that history estimates each channel's incremental contribution without tracking individual users - privacy-safe by construction, and unaffected by the next browser change.

Frequently asked questions

  • Do I need to install anything?
    No - it runs on your existing Shopify + GA4 exports.
  • Is this affected by iOS or cookie changes?
    No - it uses aggregate first-party data, not user-level tracking.
